According to researchers from Australia’s national science agency, the virus that causes COVID-19 can stay active on smooth surfaces like smartphones, metal surfaces, and paper money for much longer than the flu virus.

The researchers have found that coronavirus remains viable for up to 28 days albeit in a very controlled environment. This is 11 days longer than the flu virus. The researchers said that under the same conditions, the influenza virus remains infectious for just 17 days. Cloth and other porous surfaces can carry the infectious virus for just half the time or around 14 days. The team said that in their research they have proved that the coronavirus is “extremely robust” compared to other viruses.

The study concluded, “These findings demonstrate SARS-CoV-2 can remain infectious for significantly longer time periods than generally considered possible.”

This study focuses on the importance of cleaning and disinfecting phones and other surfaces. The study comes with some large caveats. It should be noted that the study was conducted at a constant temperature of 68 degrees Fahrenheit in dark conditions to negate the effects of UV light. In simple words, the study was conducted far from real-world conditions.

Moreover, the researchers have not used fresh mucous normally present with viruses on surfaces in their experiment also didn’t use fresh mucous which is normally present with viruses on surfaces and contains white cells and antibodies.

Cardiff University professor Ron Eccles told the BBC “In my opinion infectious viruses will only persist for hours in mucus on surfaces rather than days.”

Recently, even the experts downplayed the risk of coronavirus transmission from surfaces. Recently, The Centre for Disease Control (CDC) has put forward that “spread from touching surfaces is not thought to be a common way that COVID-19 spreads.” Rather, the most common vectors are respiratory droplets produced by coughing or sneezing.”

CDC has also said the “New guidelines also suggest that it can also be transmitted by airborne transmission in “poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise.”
